Bottom Line:
Multifocal osteosarcoma is diagnosed when there are two or more lesions in the skeleton without presence of pulmonary metastases.It is further classified as synchronous type when the patient is demonstrated to have more than one lesion simultaneously at presentation and is known as Synchronous Multifocal Osteogenicsarcoma (MOGS).We report a case of synchronous MOGS showing its multimodality imaging findings including nuclear scan findings with pathological correlation.

Mentions:
To establish the presence of suspected pulmonary lesions, nonenhanced computed tomography (NECT) scan of thorax was performed on a 16-slice computed tomography (CT) scanner (General Electric, Brightspeed, Milwaukee, Wisconsin, USA) from the thoracic inlet to lowermost part of diaphragm. No evidence of any suspicious lesion was noted in the pulmonary parenchyma [Figure 2c and d]. NECT bone window images demonstrated the shoulder lesion extending upto lower half of humerus and punctuate character of lesions involving right knee [Figure 2a and b].
